4 Claims.

This invention relates to coin-operated entertainment systems and more particularly to a system in which the customer has a selection of various programs of entertainment such as reproduced music, radio or television after the coin has been collected.

Various coin operated low volume entertainment systems heretofore have been made, wherein the reproducing mechanisms will respond to one or more coins of various sizes and will meter the time interval during which the service is rendered depending upon the value of the coin deposited in their coin collecting mechanisms. For example, the time interval for which service is rendered for a nickel is a unit time interval. The deposit of a plurality of nickels will start the rendition of service for a time interval equal in length to the length of the unit interval multiplied by the number of nickels deposited. Likewise, the time interval for which service is rendered for a dime is twice the length of the unit time interval. Generally the systems are used in restaurants, stores or the like and are of the type wherein a low volume speaker is placed in the immediate vicinity of the custom-er such as on counters or in booths. Each coin collecting mechanism is generally incorporated in a unit together with a timing device and a speaker, while the music or voice reproducer is placed in any convenient location usually remote from said unit.

In using the early low volume systems the customer had no selection of the type of entertainment provided. In using other systems the customer had a selection of various musical compositions or of radio programs but the selection must have been made prior to the start of the metered interval.

The present invention concerns a system constructed to provide a selection of any one of a plurality of recordings, or of any one of a plurality of radio or television programs, the selection being made at any time, either before, or during, the metered time interval. Thus it will be observed that as the art has progressed the customer has received greater value for the money expended in that he has gradually received a greater choice of the form of entertainment and now may change to another selection at any time during the metered interval.

The customers take full advantage of the flexibility of the new system by often changing the selection during the metered interval. The comparatively heavy use of the mechanism increases the wear thereon. It is important that the system may be maintained easily and quickly as a defective unit is not only an annoyance to the customer but it is non-revenue producing while it is out of service.

An object of the invention is to provide a coin operated entertainment system of simple and durable construction, efiicient and dependable in action and substantially proof against misuse. 7

Another object of the invention is to provide a device in which the construction of the master entertainer unit is such that various sub-assema blies may be made easily accessible for servicing or replacement with substitute assemblies.

Another object of the invention is to provide a device in which a selector switch may make one or more contacts for initiating the production of various selections without starting the mechanism until a predetermined time interval has passed so that unnecessary wear on the equipment is eliminated.

Another object of the invention is to provide the master entertainer with a monitor speaker and selector means which will enable the installer or service man to select and play at will any of the records on its multiple turntables or to listen to anv of the radio channels to which the radio receiving sets are tuned.

A further obiect of the invention is to provide a plavback unit including means whereby its pic up ill be immediatelv returned to the starting position upon the opening of its control circuit.

A still further obect of the invention is to provide a system whereby a pluralitv of isolated reproduction units may be supplied simultaneously from a master unit.

Other objects and advantages of the invention will be apparent from the following description and from the accompanying drawings which show, by way of example, an embodiment of the invention.

The master entertainment unit is shown in Figure 3 and is enclosed in a housing ll having doors I9 and 20 which may be swung open to exposethe'mechanism of the unit. In the upper portion of the housing I! is mounted a panel 2| having various units attached thereto, such as radio receiving units 22 and phonograph ampli fier units 24. The panel 2| is pivotably and slideably mounted, as may be seen in Figure 4 wherein the unitis shown-turned forward andpulled outwardly such as for an inspectionlof the back of the panel. Pivotal supporting means are provided at each end of the panel and includes a pivot shaft.25. extending from each end of the panel 2!; the pivot shaft slideably mounted in a channel 28 having'notches 2"! for the removal of the panel from its housing; Each individual radio unit 22 and each phonograph amplifier unit 26 is connected to itscircuit by its respective plug connection-.means 28 or 30. Any of the units may be quickly'removed from the panel 2| merely by removing supporting screws 3i attaching the individual units to the front of the panel and by disconnecting the plug connection means 29 or 33.

Underneath the panel 2| in the housing I! are positioneda'plurality of dual. playback-.01: record player units 32; eachlof; which includes a. pairrof.

turntables 3.4. and 35: and pickup unitsfifi. andtlh. The turntablev and. pickup. units are positioned side'by'side on removable shel'ves;39 slideably supported within channel members 68. attached to the inner surface of the side walls of the housing H. The edges of." the: removable shelves 39 are formed of a thickness: so as; to: permit the shelves to be inserted in andremoved from the. channel members: as with a. sliding fit. At the rear of: each shelf unit. are connection plugs 5?, 58 and 59: providing for an easy disconnection of the electrical circuits-to the turntablesand pickup units, whereupon the removable shelf may be pulled forwardaand removed from. the housing, as indicatedat in Figure 3.

The. electrical. wiring: diagram of the installation. is shown schematically in Figures 5 through 10 and: will not. be; specifically described as it is believed; understanclal'ole to one skilled in the art inasmuch asconventi'onal'. diagram symbols have been used.

A schematic wiring diagram of one of the plurality of radio. receiving'sets. 22 is shown in Figure 5.. A connection plug: 28a is adapted to cooperate witlrone; of the'jacks 28b to make up the connection 29. The plug 29a has a terminal or prong, 4% for the B plus, a prong i? for the audio output and tube heater connection prongs 39 and Each of the other radio receiving sets is likewise connected by a plug" 29a to a jack The. wiring diagramof a. power supply unit 59 is shown, in Figure 6 and includes a connection plug; 51a adapted to. cooperatewith a jack 5th, the plug 51a. having: prong connections 52 and 54 for direct current and prongs? 55 and 56 for alternating current.

The wiring diagram for the dual pickup or record player unit 32 is shown in Figure 7 and includes a main connection plug 51a connecting to ajack 5Tb. The plug 57a has prong connections 57c and aid for connection to a standard current supply, 516 and 51' for connection to the starting relays for the motors, and 5111 for connection with a low voltage current supply. The pickup units 36 and 3'! have shielded plugs 5.80. and 59a running directly to jack 58b and 59b of the dual amplifier unit 2 shown schematically in Figure 8.

The circuits to each of the motor starting re lays [it] for the motors B! have a time delay unit 62 in series with the coil 63 of the relay 63. The relay coils 63 are adapted to actuate their arma tures 63a to close contacts 63b to apply current to the motors 6|. While the time delay unit may be of any conventional type, it is preferred to use a Thermistor, manufactured by the Western Electric Company, New York, N. Y. The Thermistor is a circuit element in which the electrical resistance varies with changes in temperature. It is made of a material known as a semi-conductor and which has a resistance coefficient which decreases as its temperature rises. This element may have a pair of wires soldered to opposite points of its surface, or it may be placed between two electrical conductors for series connection in the circuit. The element is heated by a small current which passes through it when it is first connected to a source of current. The element passes its rated current in three to seven seconds thereafter, depending somewhat upon its design. In addition to the time delay unit IE2, a cancel switch 34 is included in the circuit for the relay 69.

The dual phonograph amplifier unit 24 shown in Figure 8 has its main connection plug 3941 provided with audio output prongs 65 and 63, B plus prong 6?, and heater prongs 69 and I9, the plug 39a being adapted to cooperate with a jack 39b. Jacks 58b and 592) are provided to receive the output plu s 58a and 59a of the dual pickup units 39 and 31.

In Figure 9 there is shown the main wiring diagram of the master entertainment unit. This circuit includes a monitor speaker II and a monitor selector switch 12 corresponding to the selector switch 9 at each of the individual coin operated speaker units, so that tests of the various radio and playback units may be made from the master entertainer unit.

A wiring diagram for the individual coin operated sound reproduction unit 5 is shown in Figure 10. This unit includes a coin collecting mechanism schematically desi nated by the credit wheel 14 and operating a multi-contact switch 75. A speaker 15 is connected in circuit with the volume switch I4 and the selector switch 9. A multi-wire connection cable 71 is connected between the various contacts of the selector switch 9 and contacts on a terminal board 79 of the master entertainer unit. Alternatively, the various individual units 5 may have their connections connected in parallel from the master unit, or the multi-conductor cable 17 may be tapped at each unit, or other equivalent connections used. I i "T The record playback resetting mechanism is shown in detail in Figures 11 throu h 15. In Figure 11 one of the turntable units 32 is shown removed from the housing I I. One of its turntables 39 is removed while the other turntable 35 is in position. The resetting mechanism includes the relay 69 positioned on the underside of the top 8! of the turntable unit 32, a cam follower assembly 82 having a cam follower stud 84 at its inner end, and a linkage assembly 95 at its outer end connected with a lift assembly 85. Each of the turntables 34 and 35 are rotatably supported on a freely pivoted stud 8! and are rotated by motor drive wheels 89 adapted to contact the inner surface of a downwardly depending flange 99 on each turntable. Each turntable also has a turntable cam 9I positioned on its underside for engagement by its cam follower stud 84 to actuate its lift assembly 89 to reset the pickup units 36 or 37 to the starting position.

The relay 69 is of the conventional type having a coil 63 adapted to be energized to actuate its armature 63a.

The cam follower assembly is shown in detail in Figures 12 and 13 and includes a follower bar 95 having an aperture 96 at its outer end to receive an end of the linkage assembly 85. The follower bar 95 is loosely attached to the top ill of the turntable unit 32 by a bolt 91 extending through an aperture in the top 8|. Spacing means are provided to raise the follower bar 95 above the top 8| by use of washers 99 so that the follower bar may be tipped to raise and lower the follower stud 84 with respect to the cam 9|. The follower bar 95 is secured in position by a nut I99 threadedly engaging with the end of the bolt 91. By reason of its comparatively loose mounting, the follower bar 95 is also free to swing its follower stud 84 towards and away from the turntable cam 9|. The swingable movement of the follower bar 95 is restricted by a limiter Ill-I comprised of a bolt I92 securing a spacer I94 to the underside of the bar and threadedly secured by a nut I95. The limiter I9! engages in an opening I96 in the top surface 8| of the turntable unit, the opening being made of a predetermined size to restrict the swingable movement of the follower bar.

The linkage assembly includes a pair of tension members I91 and I98. Tension member It? has an angularly positioned eyelet I I9 at one end while its other end is bent downwardly to pass through the aperture 96 in the follower bar and through an opening III in the top surface 8| of the turntable unit. Lower end II2 of the tension member [91 is formed with a hook end I I4 to pass around the end of the relay armature 53a. The second tension member I98 is formed with a threaded end II5 to extend through the eyelet III! of the first tension member I91 and is adjustably secured with respect thereto by nuts H6 and III. The other end of the second tension member I98 is formed with a hook end II9 to engage the lift assembly 86.

The playback units are moved upwardly and back across to the starting edge of the record by the lift assembly 89, which has a base member I29 at ached to the top SI of the playback unit 32 by screws I2I. The base member I29 has an upwardly extending bracket I22 apertured at its upper end for a bolt I23 or other conventional means providing a pivotal mounting for an L- shaped lift lever I24. The bolt I23 is threadedly engaged by a nut I25 bearing against a Washer I29 interposed between the nut and the lift lever I24. Downwardly extending leg I28 of the lift lever I24 is apertured as indicated at I2! to receive the hook end II9 of the second tension member I98.

Forwardly extending leg I29 of the lift lever I24 is apertured to threadedly receive screw bolts I39 and I3I extending through aligning apertures in a lift lever cleat I32. Adjustment means for the position of the lift lever cleat I32 is provided by moving the cleat with respect to the screw bolt I39 as the aperture through which the screw bolt I39 extends is oversized. A washer I34 prevents the head of the screw I39 from slipping into its enlarged aperture.

A lift lever latch I35 is pivoially mounted on the lower portion of the bracket I2I by means of a bolt I36 extending through an aperture in the bracket and secured by a nut I31, a washer I39 permitting freedom of movement. The forward edge of the upper end of the lift lever latch I35 is notched to provide a hook I49 adapted to receive the end of the lift lever cleat I32. The lift lever latch I35 is apertured to receive one end of atension spring I4lhaving its other end hooked around the edge ofthebracket 522. Suit,- able spacers. I42 are-interposed between the variousparts to assure freedom of movement therebetween.

Each of the pick-up units 33 and 3'5 has'a-n extension I at its rear end adjacent to the lift assembly, thev extension being attached to. the playback unit byv screws Hi and Mdextending through aligned apertures in the extension and the playback unit and threadedly engaged therewith. The aperture about screw MS is enlarged to provide adjustment means for forward and rearwardmovement of its outwardly and downwardly turned lift arm. I ll. On the side of the downwardly turned lift arm i i! of the extension isan outwardly extending lift spacer l ltattached to the. lift. arm by a screw bolt I53. extending through the spacer and threadedly engaged in an aperture in the lift arm.

Aglidebracket I5I is positioned outwardly of each of the pickup units 35 and 3? to provide an abutment so that the pickup unit will not be moved too far from its turntable and to provide an adjustable guideway so that the pickup arm will'be correctly positioned on the record. The glide bracket I5! has a base portion 552 apertured and secured to the top 8! of the turntable unit by a bolt Ififl and nut I55. The slide bracket has an upwardly extending arm 953 with slotted openings I51 and IE8 near its upper edge to receive screws I56 and I51 threadedly engaged in apertures in an index glide I52. Washers it and IE5 prevent the screws i353 and hit from slipping through the slotted openings E52 I58. The angular position of glide edge 565 of the index glide I62 may be varied by the positions of the screws and lfii.

The cancel switch 64 is provided to be actuated when the pickup units 33 or 3i are at the end of the record to resetthe pickup units to the starting position. The cancel switch 84 is positioned in an opening Ill) in the top 8| of the playback unit and is supported by an angularly shaped base member I'II secured to the top SI by screws I72. Contact members lit and Ilb are spaced by an insulating block I76 and insulated from the base member Iii by anotherinsulatin'; block ill. The contact members are attached together and to the base member ill by suitably insulated screws I'IS. Contact member El i is somewhat longer than the other contact member I'i5 so as to be urged into the openposition by a trip screw !85. Supporting means for the trip screw Hid is provided on the pickup arms 35 and 3'? including an angular bracket I8I attached to the, pickup arm by a screw I82 and having its lower end provided with a threaded aperture to receive the screw I88 adjustably locked in position by a nut E64. The adjustment of the screw I83 is made such that the cancel switch 64 will be opened when the pickup unit is at the end of the record.

In the operation of the device a coin, such as a nickel, is placed in the slot 55 of one of the individual coin actuated sound reproducing units 5. The selector switch 9, either before the insertion of the coin, or at any time thereafter during the metered interval, may be turned to the desired contact for any of the plurality of radio receiving sets or phonograph records. As may be seen in Figure 1c, the coin actuates the usual mechanism wherein a timer unit T is started and. wherein contacts are made connecting the output of the receiving set or phonograph reproduction unit to the speaker 16. The volume control switch I 4 may be adjusted to provide the.

desired volume for the speaker I6. Depending upon the selection made, the control wire for that circuit is actuated to connect to the speaker one of the radio receiving sets which is continuously energized,- and thus will start to play instantly. If a phonograph reproduction is desired the selection is made whereupon current is supplied to the relay coil- 63 (Figure 7) through the time delay 62 to start the motor 6 I. The pickups 36 or 3'! are already in position and as the phonograph amplifying unit 24 is continuously energized, the sound reproduction will be started at the individual coin actuated speaker unit 5 as soon as the motor SI starts. It will be observed that a predetermined time interval must elapse depending upon the setting of the time delayunit 62 before the motor- M will start. In the event the customer desires to change his selection during the metered interval, the selector switch 9 is turned to the desired station or phonograph record, as indicated by the various numbers on the dial of the selector switch and a sequence of operations is started in the same manner as described above to render the new selection, the time delay unit 62 preventing the starting of the motors for the various units as the selector switch is turned so as to make contact with the various control circuits. Upon the changing of the selector switch from the contacts for one selection to the contacts for another selection, the relay coil 65 for the first selection is de-energized, dropping the armature 63a, opening the relay contacts 63b and stopping the motor 65. The dropping of the armature 63a initiates the operation of the resetting mechanism so as to return the playback or pickup unit 36 or 3! to its starting position. By reason of the circuit employed, the pickup units are always returned to the starting position so as to overcome the ob- ,iectionable wail occasioned by starting a record in the middle thereof. The operation of the resetting; mechanism may be understood by referring to Figures 11 through '16. While a playback unit is operating, the relay 60 is energized lifting its armature 63a and permitting the follower bar to tip on its mounting bolt 9'1 so that the follower stud 8a is dropped against the top 3| of the supporting unit and is thereby separated from engagement with the turntable cam 9I. Upon the changing of a selection or at the end of the metered interval, the circuit to the relay 68 is de-energized allowing its armature 63a to drop and thereby tip the follower bar 95 on. its mounting bolt 9'! sothat the cam follower stud 84 is raised to engage with the turntable cam ill which will continue to rotate by reason of its inertia after the current has been discontinued to its motor 6!. The action or the cam 9| causes the cam follower 84. to oscillate. inthe horizontal plane about its mounting 9i and applies tension to reciprocate the tension members It! and I08. In order to perform the resetting of the playback arm 36 or 37, only one movement of, the resettin mechanism is required. However, by reason. of the inertia of the, turntable 34. or 35,. several operations may be made which have no efiect on the pickup arm after it has beenrreturned to its startin position. In the operation of the lift assembly 88, a pull on the tension member I08 causes the partial rotation ofthe lift lever I 24 so that its forwardly extending leg I29 is swung downwardly to engage the lift spacer I49 which is depressed to lift the pickup unit off. from the record and simultaneously swing it into abutment with the index glide (62. The lift lever latch its cooperates with the cleat E32 to hold the lift spacer I 46 therebetween and thus hold the pickup arm 36 or 37 from sliding down the glide edge I96. The relative positions of the parts may Vary somewhat depending upon the position at which the turntable 34 or 65 comes to rest. However, the pickup units 36 or 37 will either held above the glide edge I66 or somewhere along the surface thereof so that as soon as the motor is started and the turntable moves, the lift lever latch 35 will push the spacer hit so that the pickup arm will slide down the glide 166 to the starting groove of the record. The forwardly extending le I29 of the lift lever be moved away from contact with the spacer as soon as the cam follower stud Ed has dropped away from engagement with the cam i'oilower 9! by reason of the energization of the relay which allows the cam follower stud to drop away from the cam as the low point of the cam 91 passes its follower stud. In the event a plurality of coins are inserted in one or more of the coin slots H5 or I6 and a continuous metered interval is started so that there will be a repeat play of one of the records, the playback arm will be reset when it has reached the end of the record by the action of the cancel switch in the same manner as when the selector 1 switch 9 is moved to make another selection as the cancel switch contacts are in series with the selector control contacts.

While the invention has been described and illustrated with reference to a specific embodimen-t thereof, it will be understood that other embodiments may be resorted to without departing from the inventionv Therefore, the form of the invention set out above should be considered as illustrative and not as limiting the scope of the following claims.
